Micro-pixel Avalanche Photo Diodes (MAPD), the new wave in solid state detectors

MAPD Photo-Detectors

Zecotek has developed a new compact and cost effective photo-detector for low light detection that will phase out the bulky and expensive PMT’s (photo multiplier tubes) presently used in imaging applications such as PET imaging machines, Gamma cameras and high-energy, nuclear physics experiments.

The MAPD Advantage

The new Micro-pixel Avalanche Photo Diodes (MAPD) detect very small signals and can be readily used for photon counting. They feature extremely high gain typical of PMTs (~10^5) with the advantage of low operating voltage (-70V compared to – 1000 V for PMT). The all solid-state design makes MAPD detectors compact and insensitive to high magnetic fields.

“Zecotek provides LFS crystals required for the CMS experiment as they had the necessary energy resolution and radiation hardness . In using the thin LFS crystal plates Dr. Cox and his team were able to reduce the technical and cost risks associated with measurements in such experiments.”

“Zecotek provided Cherry labs with a selection of scintillation crystals from their patented LFS-3 range. After preliminary testing Cherry labs found the crystals to have the fast decay constant they required, enhancing results for their depth-encoded PET detector designs. This combined with the competitive pricing Zecotek is able to offer made for an ideal solution.”

LFS Scintillation Crystals

Zecotek’s LFS scintillation crystals are distinguished by their combined high light yields and ultra-fast decay constant, covering a wide range of emission wavelengths, that set them apart from other industry contenders. Find out more.
